What if the biggest breakthrough in women’s health isn’t a brand-new protocol… but learning how to better apply the fundamentals to the person in front of you?

Kelly and Juliet Starrett sit down with Dr. Abbie Smith-Ryan, professor of exercise physiology and nutrition at UNC Chapel Hill, to explore what the latest research can teach us about training, body composition, creatine, and women’s health across the lifespan.

Drawing from more than 15 years in the lab – and her experience as a collegiate runner who suffered 9 stress fractures – Abbie explains how our understanding of female physiology has evolved.

They unpack how women can use body composition data without becoming ruled by the numbers, why creatine may become even more valuable as we age, whether women really need female-specific strength programs, and how to approach HIIT and recovery during perimenopause and menopause.

The takeaway? Human bodies aren’t black and white. And now that we have more tools than ever, the focus should be on finding the ones that work best for you.

What You’ll Learn In This Episode
-How Abbie’s experience with 9 stress fractures shaped her approach to training, fueling, and women’s health
-Why body composition data can be a valuable tool for tracking muscle, bone, fat, and long-term health
-What the research says about creatine for women, from muscle and hydration to potential cognitive benefits
-Why women don’t necessarily need “women-specific” strength training – and when female physiology should influence how you train
-How to use high-intensity interval training, recovery, and scaling to get results without turning every workout into an all-out effort
